PAVING RIGA – LATVIA

What are paving stones?

The term “paving stone” has several meanings. For construction, there are two main ones:

paving stone – the hard surface of a road, pavement, blind spot or similar feature or structure made of a large number of roughly homogeneous bars, most of which are rectangular in shape;
paving stones – these are the stones from which paving stones are made.

Types and material of paving stones

Depending on the materials used to produce the paving stones, it is divided into several types – concrete, clinker, granite/stone and rubber.

Concrete

This type is the most common type of paving stone used.

It is made of concrete by adding different components through vibratory casting. The technology is quite simple and requires relatively inexpensive equipment and components, so it is available for independent production.
It can be used for lining carriageways, even where there is a lot of traffic.
It has a high resistance index but is susceptible to acids. Concrete paving stones discolour when exposed to acids. Prolonged exposure to acid can cause corrosive marks on paving stones. Depending on the shapes and colours used, finished tiles can be produced in a wide variety of colours, sizes and geometric shapes. But it should be noted that it is painted superficially and with a slight defect (chip, break) unpainted elements will be visible. However, given the technology and the use of quality ingredients, such paving stones will have high performance characteristics.

Clinkers

It is made of special quality clay, fired at high temperatures until fully sintered. The mineral particles are baked to a monolithic state in a lump of clay and are then inferior to natural stone in terms of their physical properties.
It withstands moisture – it doesn’t absorb precipitation, it doesn’t fear any chemical attack, it doesn’t fade in direct sunlight and it doesn’t fear mechanical damage. It is widely used for landscaping recreational areas, pedestrian zones, parking lots and areas in front of houses. Great for designers to work with – you can give it a different shape and create a decorative ornament.
It is obtained by firing specially selected slab clays in high-temperature blast furnaces. It is not considered feasible to replicate this technology alone. Paving stones made using this technology are generally more durable than cast stones, but with less variety in shape and colour. In terms of service life, it slightly exceeds that of vibration moulding.

Granite (stone)

Granite has high strength and durability. A road paved with granite masonry can retain its original characteristics for up to 50 years, even with heavy use. It is not subject to extreme temperatures, changing seasons or high rainfall. It has a wide range of colours, fits almost all style schemes, does not crack, fade, oxidise, is environmentally friendly, healthy and reusable.

It has an aesthetic appearance and is used for paving roads, squares and cobbles.

The raw material can be directly from granite, basalt or sandstone marble.
Cobblestone production is the processing of natural stone and giving it a certain uniformity. Stone splitting machines, stamping presses and similar equipment can be used for this purpose.

Rubber

It is a new type of material, it is environmentally friendly and it is used for walking paths and garden paths. It has also found applications in children’s playgrounds, terraces and footings. This type of paving stone is non-traumatic and is therefore widely used in the landscaping of various children’s facilities.

Advantages and disadvantages of paving stones

Benefits

simplicity and lightness of masonry… It is easy to dismantle if you need to lay any utilities, and simple to install the pavement in place;
durability use due to high strength;
it is resistant to mechanical stress and abrasion;
easy to repair coating … But another plus is that repairs to paving stones are extremely rare;
not washed away by rainfall. Puddles will not form on a cobbled road if the correct paving technology is followed. Water and sediment are released into the ground between the stones;
environmentally friendly material. Compared to asphalt, which can release substances harmful to humans and the environment when heated;
paving stones have an incomparably good look, and a variety of shapes and colours. This means that it will be very easy to choose one or the other type of paving stone for any design idea.

disadvantages

higher material and installation costs compared to traditional asphalt pavements. This is also due to the fact that the paving work is carried out by highly skilled workers, with virtually no use of equipment or machinery other than manual. and the high price of natural stone.
If the paving stone is made of granite, it is also difficult to process, which means that a lot of costs are spent on its production.
the need for maintenance during operation. This is particularly important in the case of poor substrate preparation and installation of the material itself;
higher noise levels when paving with automotive equipment;
Low wheel grip from traffic on cobbles, especially when wet;
discomfort when walking, mainly affected by high-heeled shoes.

Areas of activity for paving stones

The high performance characteristics of paving stones allow them to be used for paving in a wide variety of locations. The most commonly used paving stones are:

on footpaths and pavements… The pavement is rightly one of the most durable, allowing even heavy special vehicles to drive over it if necessary. It also has a very attractive appearance, which is very important for a modern city or other urban area. An added plus is that the paving can be easily dismantled during the repair or installation of utilities and reinstalled when the work is finished;
on building plinths… To make the building more attractive. In addition, paving is much more reliable than conventional asphalt concrete when paving requirements are met;
parking lots, garage driveways… In this case, it is important to consider two factors. For pavements that will be used by heavy traffic, tiles of the appropriate strength should be selected and the substrate should be prepared more thoroughly;
Landscape design… Paving stones are very actively used for landscaping: in suburban areas, gardens and orchards, parks, recreational areas, etc. The variety of tile shapes and the availability of different colour solutions make it possible to meet any customer’s requirements with a consistently high level of reliability in the quality of the coating and the elements produced.

Paving technology

Pedestrian zone layout

Site marking produced …
The topsoil is removed, but it is removed at an angle so that the water does not run under the road and down to its edges.
Priming compact… A special tool is used for this. For example, seals, pneumatic or electric seals. Or you can use a home-made shredder in an ordinary summerhouse.
Once the base has been compacted to a high quality, it is covered with layers of crushed stone or gravel. The sealing is then carried out again. The layer thickness should be up to 10 cm. The crushed stone will act as drainage and all the water will pass through and soak into the soil. A layer of crushed stone can only be dispensed with if the paved surface is protected from precipitation by a roof of some kind, for example in a recreation area where a summer house is located.
Place the gravel on top of the cement-sand mortar (3 to 1) and the kerbs are laid.
The next day, a sand cushion is created. It must be at least 10 cm thick.

River sands without clay are best. The sand layer is carefully smoothed and thoroughly wetted with water until puddles appear. Then it must be clamped and fastened.

The final stage is the laying of paving stones in accordance with the chosen future track design. They put it down with a hammer.
After all the canvas has been laid, it is necessary to go through the discarded canvas to seal the paving stones.
At the end you need to move the surface fine sand, this will fill the gaps between the parts and hold them together.

Creation of a blind area

The location of the blind zone around a residential building follows the same principle. However, there is one important difference. After all, the main purpose of the blind areas around the house is to drain the fund. To do this, the soil must be covered with a plastic casing or another form of waterproofing before the crushed stone layer is … And it is important not to forget to make the slope of the house wall.

Creation of a zone for passing or parking of light vehicles

The technology of donation in this case differs from the above methods:

crushed stone 15-20 cm thick;
sand cushion up to 15 cm
After the sand has been moistened and compacted, pour a dry layer of cement-sand mixture (in a ratio of 6 to 1) up to 5 centimetres;
after the paving is completed, the surface is richly spilt with water to harden the cement;
after the last grinding, the surface is no longer compressed by the vibrating plate;
in this case it is better to use mechanised platelets. Manual clotting is not sufficient;

Paving for heavy traffic

After the crushed stone layer has been laid, a mould up to 15 centimetres thick is erected and concrete poured. You can also reinforce the concrete with mesh in the thickness of the concrete. Prejudice. A cement-sand mortar up to three centimetres thick is applied on top. The paving stones are laid after the concrete base has hardened. After the surface has hardened, the joints are filled with a mortar mix specially selected for paving stones.

With this easy-to-use material, you can lay out your suburban area, paths, blind spots, garage and driveway and they will have a new, finished look.
